Compact Modular Sectional Design

ABSTRACT

This particular invention accomplishes the objective of flat small packing by means of having a wedge shaped corner piece that allows the adjacent back pieces not to be angled thereby reducing package size 30%. There is flap on the bottom of the sofa base pieces that can fasten and enclose a hollow space inside of the base. Sofa backs, cushions, tools and parts all can be placed inside of the sofa base during storage and shipping inside of a box optimally made of cardboard. The box only needs to be big enough to contain the base piece. The sofa back can then be attached to the seat frame by metal threaded rods. The arms can be attached to the sides using the hardware and the cushions put in place. Supporting legs are screwed onto the bottom by hand and the sofa is complete.

BACKGROUND OF THE INVENTION

This invention falls within the field of knock down sofa kits which fit within a relatively flat rectangular box so that they may easily be stored in warehouses and transported. Inventive means of enclosing the kit in the smallest, flattest box are desirable because of the need for stable storage using the least amount of space. Further characterization of the relevant field would be that the invention falls in the field of sofa kits that can be readily assembled at home by the end user.

BRIEF SUMMARY OF THE INVENTION

This particular invention accomplishes the objective of flat small packing by means of having a wedge shaped corner piece that allows the adjacent back pieces not to be angled thereby reducing package size 30%. There is a flap on the bottom of the sofa base pieces that can fasten and enclose a hollow space inside of the base. Sofa backs, cushions, tools and parts all can be placed inside of the sofa base during storage and shipping inside of a box optimally made of cardboard. The box only needs to be big enough to contain the base piece. The sofa back can then be attached to the seat frame by metal threaded rods. The arms can be attached to the sides using the hardware and the cushions put in place. Supporting legs are screwed onto the bottom by hand and the sofa is complete.

DETAILED DESCRIPTION OF THE INVENTION

This particular invention accomplishes the objective of flat small packing by means of having a wedge shaped corner piece that allows the adjacent back pieces not to be angled thereby reducing package size 30%. There is a flap on the bottom of the sofa base pieces that can fasten and enclose a hollow space inside of the base. Sofa backs, cushions, tools and parts all can be placed inside of the sofa base during storage and shipping inside of a box optimally made of cardboard. The box only needs to be big enough to contain the base piece. The sofa back can then be attached to the seat frame by metal threaded rods. The arms can be attached to the sides using the hardware and then cushions added. Supporting legs are screwed onto the bottom by hand and the sofa is complete.

Turning now to FIG. 1 , the manner is shown by which one chair back (1) may be joined with another chair back (1) using a wedge piece (2) that forms a back with an arm. Note that the arms (1) and the wedge piece (2) also have bore holes for metal threaded rods (3). The wedge piece (2) can be assembled into the base piece (4) as shown by FIG. 11 using assembly washers (5), lock washers (6), nuts (7) and the tool (8) to engage with the metal threaded rods. Turning now to FIG. 12 , a fully assembled corner chair module can be seen with feet (9) attached and with its cushions (10) in place. The backs, cushions, feet, tool, and parts can all be stored inside the base piece while the kit is being shipped in its box. Ottoman modules, chair modules and corner chair modules can all be assembled into more complex furniture configurations. Turning now to FIG. 4 , the manner of attaching the feet (9) to the base piece (4) can be seen. The feet (9) are screwed into the bottom of the base piece (4) through holes that are located at the corners of the base piece bottom. A foot washer (11) may be placed between the foot (9) and the base piece (4).

Turning now to FIG. 5 , the base piece (4) is shown to have a flap (12) at the bottom which is open in this drawing to show the support bands (13) that help support the upper part of the base piece (4). The flap may be closed and a closure means such as hook and loop fastener may be used to hold the flap in its closed position. Turning now to FIG. 6 , the base piece (4) can be seen to hold items such as a cushion (10) and a parts box (14) that are placed in there prior to closure of the flap (12). Turning now to FIG. 7 , the wedge piece (2) can be seen to be substantially an elongate rectangular cuboid having a first rectangle (15) and a second rectangle (16) which are joined at a first edge (17). The wedge piece (2) also has a top end (18) which is joined to the first rectangle (15) by a second edge (19) and is joined to the second rectangle (16) by a third edge (20). A bevel face (21) is formed by a slice originating at a line segment (22) connecting the second edge (19) and the third edge (20) and proceeding at an outward angle along the long axis of the wedge piece (2) until the plane of the bevel face (21) meets the first edge (17).
